Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of tea processing equipment, in particular to a kind of multiple synchronous rotation's oolong tea making machine. BACKGROUND

[0002] Making green is one of the key processes of manufacturing oolong tea, and making green can properly regulate water evaporation and internal decomposition during wilting. The leaves are subjected to mechanical force, and the cell tissue of leaf margin is damaged, which promotes the oxidation, polymerization and condensation of polyphenolic compounds, produces colored substances and promotes the formation of aromatic compounds. Making green includes two processes of airing green and shaking green (the spread of oolong tea is airing green, and shaking is shaking green). The leaf tissue enhances cell water absorption due to vibration, improves the transport function of the transport tissue, and the water in the stem is transported to the leaf through the leaf vein. The aromatic substances in the stem are transferred to the leaf with the water, and the water-soluble substances accumulate in the leaf. Due to the penetration of water in the stem vein to the leaf, the leaf returns to the swollen state after shaking, which is called returning green, commonly known as returning sun. After shaking, it enters the airing green, which is also called standing, waiting, airing green. During the airing green process, the making green leaves are in a relatively stationary state, the leaves continue to evaporate water, the leaves lose water, the stem replenishes less water to the leaves, and the leaves are in a wilting state, which is called returning green. During the making green process, the leaves undergo chemical changes during wilting, the green color gradually fades, and the edge gradually turns red. Through 5-7 times of alternating airing and shaking, when the leaves show red edges (vermilion red), green (or yellow green) in the middle, transparent veins, shape like a spoon, stiff appearance, soft feel, and emit strong fruit, osmanthus or orchid fragrance, it is the appropriate degree of making green.

[0003] The applicant of the present application applied for and was granted a "Linkage Type Oolong Tea Shaking Machine" with publication number CN204653628U in 2015, which includes a rack with two vertical supports and four rotating drums horizontally arranged between the two supports. The four rotating drums are driven to rotate by a chain wheel driving mechanism arranged at the back side of each drum. Each drum is provided with an openable drum cover. The linkage type oolong tea shaking machine can achieve natural water evaporation without additional heating and blowing, and can simulate the effect of artificial shaking. However, the patent requires airing after shaking, which means that the tea leaves in the drum need to be manually removed for airing, and then need to be placed back in the drum for shaking again after airing. The above-mentioned equipment can realize the mechanical shaking of multiple drums, but the overall making green efficiency is still low, and the manual workload is still large. SUMMARY

[0036] When the turnover plate is turned to close the open window, the two turnover plates 4 and the air-permeable arc-shaped plate 202 form a complete cylindrical wall surface of the rotating drum (which can be a cylindrical wall surface or a polygonal cylindrical wall surface), and when the turnover plate is turned to open, the turnover plate and the bottom of the rotating drum form a support surface for spreading and airing the green leaves, i.e., the green leaves are spread and aired on the turnover plate 4 and the bottom of the rotating drum, and the proportion of the turnover plate 4 in the entire circumferential direction of the rotating drum is 1 / 5-1 / 3.

[0037] The turnover plate can be an arc-shaped plate or a flat plate, and one side edge of the turnover plate is connected to the outer drum wall (the edge of the air-permeable arc-shaped plate 202 or the open window 3) of the rotating drum through a plurality of hinges to enable the turnover plate to be turned outwardly, and of course the turnover plate can also be rotated through a rotation shaft penetrating the two side wall plates of the turnover plate.

[0039] The two side wall plates 201 can be round wooden plates, and a central shaft 5 is fixedly connected to the center of the outer side of each of the round wooden plates (or the two ends of the central shaft 5 penetrate through the two side wall plates 201 and extend out of the two side wall plates 201, and the two side wall plates 201 are supported and fixed by the air-permeable arc-shaped plate 202), and the vertical rod 102 on the two vertical supports 1 supports the central shaft through a bearing seat 6.

[0040] The air-permeable arc-shaped plate 202 includes an arc-shaped frame 9 fixedly connected between the two side wall plates, and an air-permeable net is laid on the arc-shaped frame, which can be a metal net, a stainless steel plate densely provided with holes, or a net woven from rattan.

[0041] The arc-shaped frame 9 includes a plurality of wooden strips 901 vertically connected between the two side wall plates and a plurality of intermediate connecting strips 902 for supporting the air-permeable net connected between the plurality of wooden strips (the intermediate connecting strips 902 can be steel strips, and the intermediate connecting strips 902 are in the shape of a circular arc and form a skeleton for supporting the air-permeable net together with the wooden strips 901), and the wooden strips protrude from the inner surface of the rotating drum to become guide vane strips for stirring the green leaves when the rotating drum rotates, and the arc-shaped frame 9 is limited between the two side wall plates.

[0042] Of course, the guide vane strips (wooden strips 901) can also be made of metal strips or bamboo strips, etc.; the cross-sectional shape of the guide vane strips can be rectangular, triangular, semicircular, etc.; and preferably, the guide vane strips are installed at the position of the edge of the open window (i.e., the edge of the air-permeable arc-shaped plate 202, which is a frame strip of the air-permeable arc-shaped plate 202), so that when the machine is stopped and the turnover plate 4 is about to be opened, the green leaves located in the area of the turnover plate 4 will not directly slide to the bottom of the rotating drum, thereby reducing the workload of subsequently shoveling part of the green leaves from the area at the bottom of the rotating drum into the area of the turnover plate 4.

[0043] The turnover plate can also be composed of two wooden strip bodies 401 and a plurality of intermediate connecting strip bodies 402 (arc-shaped wooden strips or steel strips) for supporting the air-permeable net layer 403 parallelly connected between the two wooden strip bodies.

[0044] In order to limit the turning amplitude of the turnover plate, the end edges of the turnover plate are provided with side plates 10, the inner side of each side plate is provided with a hook 11, and the two side wall plates of the rotating drum are provided with flanges 12 for limiting the hook, so that when the turnover plate is opened, the hook 11 is limited by the flanges 12, and the turnover plate cannot continue to turn down; the turnover plate includes two side plates 10 (close to the two side wall plates 201), two horizontal strips vertically fixedly connected between the two side plates 10, and a plurality of longitudinal strips (in the shape of an arc) perpendicular to the two horizontal strips, and an air-permeable net is laid on the two horizontal strips and the plurality of longitudinal strips, which can be a metal net, a stainless steel plate densely provided with holes, or a net woven from rattan, and the horizontal strips are connected to the wooden strips 901 of the air-permeable arc-shaped plate 202 through a hinge.

[0045] In order to enable the stable connection of the turnover plate to the drum when closed, a buckle structure is arranged between the free end of the turnover plate and the drum, which includes a lug 13 with a hole arranged on the free end of the turnover plate and a bolt 14 arranged on the breathable top plate. When the turnover plate is closed, the bolt is inserted into the hole of the lug to achieve the stable closure of the turnover plate.

[0046] In order to avoid the leakage of tea leaves from the drum, a blocking strip 15 is arranged at the gap position between the turnover plate and the drum wall to prevent the leakage of tea leaves. The blocking strip 15 can be a plastic sheet, a wood sheet or a metal sheet, etc.

[0047] In order to enable the turnover plate to have a certain resistance after being turned over, so as to make the turnover more stable, a support rod 16 is arranged between the outer surface of the turnover plate and the drum. The first end of the support rod is hingedly connected to the first support 17 on the outer surface of the turnover plate 4. A guide channel 18 is arranged on the outer surface of the drum. The guide channel 18 is formed by bending a steel strip into an arc shape, and the two ends of the steel strip are welded on the outer surface of the drum to form the guide channel 18. A screw rod 19 is arranged in the guide channel. A bearing 20 is sleeved and arranged on the middle part of the screw rod 19 to slidably cooperate with the guide channel. The second end of the support rod is locked and connected to the two end parts of the screw rod 19 through a nut 24. A second support 21 is arranged on the outer surface of the drum. A tension spring 22 is arranged between the second support 21 and the screw rod 19.

[0048] The second end of the support rod is fixedly provided with two spaced apart fork rod parts 23, which form an included angle of 90-170 degrees with the support rod 16. Figure 9 The bearing 20 is arranged at a position between the two fork rod parts 23 (the steel strip is also limited between the two fork rod parts). The screw rod 19 penetrates through the bearing 20 and is hingedly connected (rotatably connected) to the fork rod parts 23 (as shown in the Figure 10 The nut 24 is locked on the end part of the screw rod 19. The first end of the tension spring 22 is connected to the position where the screw rod penetrates the fork rod part. The second end of the tension spring 22 is connected to the second support 21. When the turnover plate is turned over, it is supported by the first end of the support rod 16. The support rod abuts against the steel strip at the intersection position with the fork rod part. The second end of the support rod is pulled by the tension spring 22, so that the position where the support rod contacts the steel strip serves as a support point. The support rod has a tendency to hinder the turnover plate from being turned over, thereby buffering the turnover of the turnover plate and avoiding the situation that the tea leaves fall out of the drum due to the rapid turnover of the turnover plate.

[0049] The drum 2 installed on the rack 1 of the present application needs to ensure that the turnover plate does not contact the ground after being turned over.

[0050] The working method of the oolong tea making machine with multiple groups of synchronous rotation is as follows: the turnover plates of the rotating cylinders are turned over to make the open windows in an open state, the tea leaves are poured into the rotating cylinders, the turnover plates are turned over to close the open windows, the rotating cylinders are synchronously rotated under the action of external power (a driving mechanism), the rotating cylinders stop rotating after rotating for a certain time, the turnover plates are turned over to make the open windows open, at this time, the green leaves are spread on the bottom of the rotating cylinders or the turnover plates (if the green leaves are concentrated on the bottom of the rotating cylinders, a tool can be used to scrape out part of the green leaves to the turnover plates), at this time, the airing process of the tea leaves is implemented, the green leaves spread on the turnover plates and the bottom of the rotating cylinders are aired for a certain time, the turnover plates are turned over to close the open windows, the rotating cylinders are started to rotate again, and the above steps are repeated for several times, so that the whole making process is completed, the making of the tea leaves by using the device realizes the synchronous rotation of the four rotating cylinders, and the tea leaves do not need to be repeatedly taken out of the device, spread and poured by manual work, so that the working efficiency of the making is greatly improved, the labor is reduced, the labor intensity is reduced, and the quality of the tea leaves is also beneficial to be ensured and improved.
